Tom has two pendulums with him. Pendulum 1 has a ball of mass 0.2 kg attached to it and has a length of 5 m. Pendulum 2 has a ball of mass 0.6 kg attached to a string of length 1 m. How does mass of the ball affect the frequency of the pendulum? The mass of the ball of the pendulum is inversely proportional to the period; hence it will affect the frequency of the pendulum. The mass of the ball of the pendulum will not affect the period; hence it will not affect the frequency of the pendulum. The mass of the ball of the pendulum is directly proportional to the period; hence it will affect the frequency of the pendulum. The mass of the ball of the pendulum is directly proportional to the square of the period; hence it will affect the frequency of the pendulum. Which pendulum will have a higher frequency and why?
